Description Usage Format References

These data relate to an engineering application where two metal sheets are compressed by water-cooled copper electrodes under an applied load L and the resistance spot welding is measure. Two data sets are provided, one containing observations from the real experiment (`spotweldfield`

) and another one containing observations from the simulator (i.e. the computer model, `spotweldmodel`

).

Details about this data set can be found in Bayarri et al (2007).

Two data frame with observations on the following variables.

`load`

Controllable input (Load)

`current`

Controllable input (The direct current of magnitude supplied to the sheets)

`thickness`

Controllable input

`diameter`

Response variable (Resistance)

`tuning`

Calibration input (hence only in

`spotweldmodel`

)
